摘要
针对受干扰信号影响,RFID读写器天线组网中易存在吞吐量和分组交付率较低等问题,提出一种新的超高频RFID读写器天线组网方法。通过压缩小波对超高频RFID读写器实行同频干扰处理,提升读写器的抗干扰性效果,离散化处理RFID读写器天线传播模型,通过离散点阵的形式描述读写器部署问题。引入粒子群优化算法将读写器部署问题转换为离散优化问题,使用粒子群优化算法求解,得到最优结构和尺寸,实现超高频RFID读写器天线组网。实验测试结果表明,所提方法的分组交付率较高,吞吐量较大,可以获取比较满意的超高频RFID读写器天线组网方案。
In order to solve the problem of low throughput and packet delivery rate in RFID reader writer antenna networking due to interference signals, a new UHF RFID reader writer antenna networking method is proposed. At first, UHF RFID reader was subject to the co-channel interference through compressed wavelet, and then the anti-interference effect of the reader can be improved. After that, the propagation model of RFID reader antenna was discretized. Moreover, the problem about reader deployment was described in the form of discrete dot-matrix. Furthermore, the particle swarm optimization was used to convert the problem of reader deployment into a problem about discrete optimization. Meanwhile, the particle swarm optimization was used to solve the problem, and thus to obtain the optimal structure and size. Finally, the networking was achieved. Experimental results show that the proposed method has high packet delivery rate and large throughput, and can obtain a satisfactory networking scheme of UHF RFID reader antenna.
